Today I installed Fedora 14 in a different partition in the same hard drive as Ubuntu. At the Fedora 14 installation, I chose not to install Boot-loader in the MBR, and instead chose to install it in the Fedora partition itself, which is according to my HD layout /sda3.
After the Fedora 14 installation I booted in to Ubuntu and ran
sudo update-grub
but 'grub.cfg' fails to add Fedora 14 in to the OS list. Here is the output of boot-info script.
Boot Info Script 0.60 from 17 May 2011

=> Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and looks

According to this Fedora 14 is visible in sda3. Does anybody know a way to add Fedora 14 to grub.cfg of Ubuntu so I can choose which OS to boot? Thanks in advance.
Best Answer
The easiest way to boot Fedora would be to add an entry to grub.cfg that chain loads to Fedora's copy of Grub.
Create a file
/etc/grub.d/15_fedorawith the following contents:Make the file executable and then regenerate the grub configuration file:
This should ensure that the menu entry stays around when the Grub configuration is regenerated.
